| Abstract;Isolable cyclic dialkylgermylene 1 and stannylene 2 reacted with 2 equivalent of TEMPO radical in benzene at room temperature to give the corresponding 1:2 adducts. A kinetic study has shown that the reaction of 1 with TEMPO obeys a second-order rate law, first-order in 1 and first-order in TEMPO. During the reaction, only TEMPO radical was observed by ESR spectroscopy. The rate constant of the addition of TEMPO to germylene 1 was estimated to be 7.3*10-3M-1s-1 at 273K, which was slower by 1011 times than those of additions of TEMPO to triaryl and trialkyl germyl radicals.
